Every plan includes $20/mo in free credits for telemetry (equal to 10 million logs, spans, and metrics). - **No hidden fees:** Consumption billing — you pay your plan cost plus $2 per additional million records above the included credits. No other line items. - **No surprise bills:** Contact us to set a hard price cap on your account. When you hit it, ingestion pauses so your bill never exceeds what you approved.

Spans have start and end times, attributes (key-value metadata), and can nest under parent spans. Multiple nested spans form a trace, representing a complete request flow or operation. **Metric:** A collection of datapoints at intervals. When stored with timestamps, metrics become timeseries. Metrics show trends across your system; traces show what happened in a specific request. --- ## Usage notes **5KB average span allowance.** Logfire allocates 5KB (5,120 bytes) per span or metric, averaged across your usage over time. Actual spans are normally under 1KB. Logfire will contact you if you frequently exceed this. **What happens if you exceed the free allowance.** On Personal, Logfire sends email and in-app alerts, then eventually stops ingesting new data. On Team, Growth, and Enterprise, you are charged at the plan rate for additional usage. **Price cap.** Team and above plans can set a spending cap. Once you hit the cap, new telemetry is hidden from view but kept for a generous threshold. Raise the cap anytime to unlock your data. To set a cap, email accounts@pydantic.dev. **Personal plan in production.** Yes, the Personal plan works in production. Data is lost if you exceed the free allowance, but there is no other restriction. **Data retention.** One month by default on Personal and Team. Up to 90 days on Growth. Custom (unlimited available) on Enterprise. --- ## Discounts Financial support is available for non-profits, academics, community groups, and pre-funding startups. Complete the form at https://pydantic.portal.usepylon.com/forms/startup-non-profit-app for a substantial discount. --- ## FAQ **What is a guest?** A guest is a read-only user invited directly to a Logfire project (not to an organisation). Guests are similar to outside collaborators on GitHub. **Will Pydantic (the library) remain free?** Yes. The Pydantic data validation library is, has always been, and always will be free under the MIT license. Prices on this page apply to Pydantic Logfire only. **Can I pay for extra usage on the Personal plan?** No. Ad-hoc payments for additional records are not available on Personal. Upgrade to Team to go beyond 10M records. **I was on the Pro tier. What happened?** Pro has been replaced by Team and Growth. Unmigrated organisations have data ingestion paused (no data is lost). Subscribe to a plan to restore access. **How long is data stored?** Personal and Team: 30 days. Growth: up to 90 days. Enterprise: custom (unlimited available). **Is there a free trial for paid plans?** Team includes a money-back guarantee for your first month. **Can I self-host Logfire?** The SDKs are open source. The server and UI are closed source. Enterprise plans include self-hosted deployment options.
